Gentamicin, sold under brand names Garamycin among others, is an antibiotic used to treat several types of bacterial infections.[1] This may include bone infections, endocarditis, pelvic inflammatory disease, meningitis, pneumonia, urinary tract infections, and sepsis among others. It is not effective for gonorrhea or chlamydia infections.
Rod Details. The rods are the most numerous of the photoreceptors, some 120 million, and are the more sensitive than the cones. However, they are not sensitive to color. They are responsible for our dark-adapted, or scotopic, vision.The rods are incredibly efficient photoreceptors.owever, they are not sensitive to color. The 6 to 7 million cones provide the eye's color sensitivity and they are much more concentrated in the central yellow spot known as the macula. In the center of that region is the  fovea centralis , a 0.3 mm diameter rod-free area with very thin, densely packed cones.
Making the world better, one answer at a time. The receptors are arrayed along the back of the interior of each eye, in the tissue called the retina. There are two types of cells that act as photoreceptors in the eye: rods and cones.Rods detect only the presence or absence of light without distinguishing between colors, thus giving black and white vision (as at night).here are two types of cells that act as photoreceptors in the eye: rods and cones.
